STUBBLE TORCH.

Application filed July 14, 1924. Serial N0. 725,974.

To all whom t may concern.'

Be it known that l, JOHN D. KALvnnUD, a citizen of the Dominion ofCanada, residing at Plaza, in the county of Mountrail and of which thefollowing is a specification.

This invention relates to torches for burning stubble, grass, etc.

The object is to provide a simple, strong 5 1 and durable burner for theabove stated purpose, which maybe easily handled and operated to ignitethe stubble or grass around a relatively large area without thenecessity to stoop or bend over to reach the same, or to keep constantlyon the move to reach other areas.

Another object is `to provide a burner or torch ofL this character whichmay be easily supported in the hands of the operator, at the end of along handle, in proper positionV to bring the ignition means close tothe surface of the ground, and spaced sufliciently from the tankcontaining the fuel oil to avoid danger of explosion.

' A final object is to provide a torch orv hui-ner of this class' whichmay have one or more separate igniting members 1n the form Vof wickscapable of maintaining flames suf-. fieiently in advance of the fueltank as tov be readily and constantly observed by the operator, the saidtank being formed to provide a base or rest for the device when not inuse, and to prevent the same from turning over as well as 'to supportthe flame ends of the wicks above the ground. j

A full and complete understanding of the Y invention may be obtainedfrom a consideration of the following detailed description,

taken in connection with the accompanying of the improved torch, thesupporting and operating handle being broken away;

Figure 2 is a perspective view of the device drawn on a smaller sca-le;

Figure 3 is au elevation of the front end drawn on the same scale asFigure l;

' Figure el is a. view similar to Figure 2 but showing a slightmodification of the invention.

Referring to the drawing, there is shown a tank l formed of suitablesheet metal and having a capacity for sufficient kerosene oil to burnfor a considerable length of time, say one-half day, which will enablethe 0perator to burn the grass or stubble from a relatively large areaof ground without the necessityv for refilling the said tank. As shownin Figures 2, 3 and 4, the tank is substantially triangular in crosssection,

having a front wall 2, and a corresponding rear wall 3, each of' whichhas its apex rounded on a relatively large circle, the sheet metal ofthe body proper following such arc, as at Zi, while the other angles 5of the triangle are rounded on a smaller radius and join the inclinedside walls to the flat base wall 6. Any desired method of joining thewalls of the tankV together may be employed to secure a strong, durableand leak-proof container. v

Arranged in longitudinal alinement upon the apex 4 of the tank, thereare secured, as

yby riveting, brazing or otherwise, a pair of yspaced sockets 7, whichmay be formed of strips of sheet metal bent into substantially roundform and having their terminals formed into attaching flanges for thepurposes, said sockets being located adjacent to the end wallsrespectively, as clearly shown in Figures l and 2 of the drawing.

The rear wall 3 is provided adjacent to the apex thereof, with a fillingopening 8, having an outwardly-extending, threaded flange 9 surroundingthe same, the latter being adapted to receive an ordinary threadedclosure cap 10 in the usual manner and for the usual purpose. Y L" Thefront wall 2, in the simplest form of the invention, as illustrated inFigures l, 2 and 3, is provided with an opening l1, located in line withthe center of the apex and adjacent to the base 6, said opening beingreinforced by a plate `l2 riveted or otherwise secured to thegexterorface of the front end Wall 2. The plate is also provided with anoutstanding flange having a `threaded bore or passageway 13 registeringwith the opening 11 in the end iva-H2.

A metallic tube 14, preferably somewhat longer than the, tank ligand;threaded atone end, is screwed into the aforesaid'passage- Way 13, andextends horizontally, outward in front of the tank, the same beingelevated above the base Wall 6 of said tank, Vso that When the tank isresting upon the ground or other support, Ythe open end of the tube 14:is held in spaced relation thereto by means of the Weight of anelongated handle 15 having one. end' secured in the aforesaid*Y sockets7, While the other, free end rests upon the said support throughgravity. The handle, 15 is formed lof suitable, light, strong Wood andmaybe friction'ally held in the scckets, or aynail or nails may beeinployed to prevent the handle from becoming detached from thesockets.'

cess Iportion of the wicking being inserted through the opening l1 andremaining Within the tank` to be constantly submerged in the oil' orotherfuel contained therein. The

` outer end ofthe Wick may be drawn out'the to' required distance togive the desired llame in theusual manner. n v

The construction of all Vthe parts las thus f ar described is preciselythe same in Figure Land the same reference numerals are also employed todesignate the parts, the difference in' construction being, however,that in place ofthe single, centrally-located Wick tube, there aretivoof such `tubes having Wicks therein located at opposite sides of thecenter of the front end WallQ, and substantially at the centers of therounded cornersat the base of the tank.

- iIn each form of the device, the wicking fills Athe tubes snugly soasto convey the oil or other liquid' fuelto the llame end of the saidtubes'l and at thesaine time, by reason of such tit, prevent the fluidfrom flowingV freely through and outy of the open end to Waste thesaine, or possibly cause an explosion. V Y

The handle 15 maybe any desired length to enable thel koperator toconveniently handle Vthe device and reach out as far as possible Withoutunduly tiring himself, and,AA

assuming that the tank is appropriately charged and the ivick set andignited, it is only necessary t'o stand in one position', with thehandle grasped in both hands near the free end of, thelsame and thetorch may `be applied to any or all parts of a given area Without`bending or stooping and1 While standing in n'ekposition, as will bereadily understood. The pressure of the oil or AotherV fuel, in thetank, being aboveV the outlet having the wick?, insures a steady pres-Suitable wicking 16 1s drawn through the tube liliby any Well-knownmeans, the ex` sure at the flame end and causes a uniform flame, and, bysuspending the tank beneath the supporting handle, it Will be seen thatthe lowermost point of the deviceV is the end of the tube or tubeshaving Vthe flame, and since said tube orntubes are held insubstantially a horizontal position, in advance of the tank, there isnothing to hinder the applicationof the flame to thegrass or stubble',and nothing to interfere with the vision of the operator who may seejust Where to apply the torch in a considerable circle about himself.

F rom the foregoing itivill be seen that a simple, cheaply-inanufacturedand strong and di'irable' torch has been provided for the Cil abovestated purpose, which may be easily Filled With `fuel suilicientto lasta relatively long time g that the device may beeasily and naturallycarriedo'r supported in the propelI position to apply the flame, andthat` the` latter is constantly fed, as long` as the supply of `fi'ifellasts, by the pressure of the Weight of the fuel within the tank, theflame being-spaced suliicient distance toprevent any danger from theheat thereof. Vhat is claimed is Y 1. A torch `comprising an oil tankhavin a front and a rear Wall and a" substantially flat' base, anelongated handle, means provided at thev top ofA thetank on the outsidelUO the tank adjacent to the base of the tank and communicating with thelatter, saidtube being located substantially parallel tothe ilat base ofthe tank, a Wick mounted in and tightly fitting said tube, thearrangement of "the liandle and the Awick tube at opposite sideso'f'th'e tank serving to balance eachl other When the base of the tankis resting` on the ground 2. A stubble torch, comprising an oil tank ofsubstantially triangular cross-sectional area, said tank having a frontand a rear end wall,4 spaced, alined sockets mounted on the apenl of thetriangular tank, an elongated handle having one end fitted in thesockets and extending beyond to the rear of the tank, said rear end Wallhaving a `filling openingat a high point of the tank and prol* videdWith a closure cap, a straight tubular Wick holder extending forwardlyand longitudinally from the front end Wall of the tank and locatedadjacent, to the base of the triangular-,end Wall, said tube beingconsid 'erably longer than the tankaiid communicating therewith, and awick mounted in and tightly ntting vthe tube to Cenvey oil from the tankto the free end thereof andto prevent leakage of the oil, thearrangement of the handle and the Wick tube at opposite sides of thetank serving to balance each other when the base of the tank is restingon the ground.

3. A stubble torch comprising an oil tank of substantially triangularshape in cross section, one of the sides of the triangle forming a base,spaced straps forming sockets and secured to the apex of the triangulartank, an elongated handle having one end secured in said sockets andprojecting rearwardly from the tank and constituting a handle, the rearWall of the tank having a filling opening at a high point of the tankand provided with a Closure cap, spaced straight Wick tubes extendingforwardly and longitudinally from the front wall of the tank, adjacentto the base thereof and communieating with said tank, and a Wick in eachtube and tightly fitting the same to feed oil to the outer ends of thetubes and to prevent leakage of the same, the arrangement of the handleand the Wick tube at opposite sides of the tank serving to balance eachother when the base of the tank is resting on the ground.

In testimony that l claim the foregoing as my own, have hereto aflixedmy signature.
